Nine of the 11 starters on Oregon's offense Saturday night didn't play a single snap two years ago when the Ducks made their perfect march to the BCS National Championship Game.

So being 10-0 last week, ranked No. 1 in the polls and being just three victories from a trip to Miami for this season's national title game was, well, it was all new.

Chip Kelly's approach early in the week was different, too, according to UO insiders, one of which described the coach as "nervous" in the days before the game.

Frustrated that injury details and practice information -- such as De'Anthony Thomas' participation on defense -- were being reported in The Oregonian, Kelly "was on a mission" early in the week to find out where "the leaks" were coming from, a UO source said.

Kelly "made a loose threat" to the team after practice Tuesday about possible repercussions if he found out who was talking off the record.

"It was messed up," another UO source said.

The Ducks, Kelly has often said, pride themselves on their preparation. They practice fast and hard, and often talk about not letting outside influences affect their performances.

Oregon's practices are closed to the public, and Kelly is notoriously tight-lipped about injuries. The Ducks have had enough of them lately that they could broadcast their own "M*A*S*H*" episode.

"Stanford played better than us," Kelly said. "Everybody has to deal with that (injury) stuff."

It was an uncharacteristically quiet night for the UO offense.

Oregon, averaging 54.8 points per game, was held to a season-low 14 points; it was the second-lowest point total of Kelly's tenure as head coach (the lowest being his debut in a 19-8 loss at Boise State).

The Ducks were 0 for 2 on fourth downs against Stanford, after converting 14 of 19 attempts in the first 10 games. Oregon's vaunted running game, which averaged 325 yards, was held below 200 yards (198, to be exact) for the second week in a row.

Senior running back Kenjon Barner was held to 66 yards on 21 carries, and will likely lose ground in his once-burning bid for the Heisman.

"Just disappointment -- that's all there is to it," Barner said. "We didn't play conservative, we didn't play for overtime or anything like that -- we played to win the game. ... We didn't execute when we needed to execute."

Take away quarterback Marcus Mariota's 77-yard first-quarter run, and Oregon averaged just 3.1 yards on their 39 other rushing attempts against a Stanford defense that entered the week No. 1 in the nation against the run.

"They showed some different fronts and then were dropping out of it," Mariota said. "That didn't leave too many holes."

Before Saturday, Oregon was 42-0 in the Kelly era when leading after three quarters.

"You have to be mentally tougher than the situation," Barner said. "You're going to lose games. Obviously, we don't lose a lot around here. You just gotta bounce back. We've been here before; we know what it feels like, and we know what we still have to play for.
